This wind slab was triggered by a snowmobiler on Buck Ridge. Although small, it's a good indication that larger slides are possible on wind loaded slopes. Photo: A. Wheeler

The crown on this slide ranges from 4-6' deep. It occurred on a heavily wind loaded slope and broke on facets near the ground. It's a clear reminder that large avalanches are possible in the mountains near West Yellowstone.

Lionhead Range, 2019-02-19

This slide occurred in the Lionhead area near West Yellowstone. It broke 4-6' deep, failing on facets near the ground. It's unknown if it was triggered by a natural cornice failure or by a snowmobiler. Either way, it's a clear reminder that large avalanches are possible in the mountains near West Yellowstone.

On Saturday (2/16) skiers in Beehive observed "Lots of natural avalanches from Friday nights snow. Notice the large cornice sections at the base of the slope. We were impressed with the size of the cornices on the ridge. We noted no collapsing or cracking on the skin up or ski down." Photo: A. Crawford

This avalanche on Crown Butte failed after multiple sleds had crossed the slope. From the email: "This one broke about 10 minutes after we’d been sledding below and across it. You can see our tracks going into it. Spooked us. The crown up top looked pretty deep, maybe 3 or 4 ft". Photo: S. Strenge

After riding all over the Cooke City area this was the only new avalanche we saw. It looks as though snow sluffing off the cliffs likely triggered a slide in the new snow from this week. Photo: GNFAC

This slide appeared to be triggered by a falling cornice. It broke near the ground and propagated two hundred feet wide. It snapped trees and left a debris pile up to ten feet deep. This avalanche illustrates that large and dangerous avalanches remain possible in the southern Madison Range and mountains near West Yellowstone. Photo: GNFAC
